1 Claim. (Cl. 132-41) This invention relates to hair curlers of the type used particularly in permanent waving, and in particular an elongated curler formed with substantially semi-circular complementary sections held together with elastic bands and separated with a wedge-like element and also in which means are provided on the outer surfaces of the devices for gripping and holding hair to facilitate winding the hair on the body of the device.

The invention is an improvement in cold permanent waving including an improved rod particularly for use in the process of making permanent waves by professoinals in beauty parlors, and which can also be used in the home for making a home permanent wave.

The purpose of this invention is to provide a hair curler in which the diameter of the curler is increased as hair is wound thereon and in which, after the hair is positioned on the curler, the diameter of the curler is reduced, thereby relieving tension in the hair to permit hair treating liquids to penetrate to all strands of hair throughout the curl.

With the conventional type of hair waving rod or curler the hair is wound tight on an elongated rod and with the hair secured in the rolled or wound condition hair waving fluids are applied to the hair on the curler, and with the hair wound tight it is dilllcult for the liquids to penetrate through the strands of hair. With this thought in mind this invention contemplates a hair curler in which means is provided for expanding the curler as hair is wound thereon and wherein, after the hair is in position on the curler, the core or body of the curler is contracted so that tension in hair Wound on the curler is relieved.

The object of this invention is, therefore, to provide means in a hair curler or rod particularly adapted for cold permanent waving wherein the diameter of the curler or rod may be reduced after hair is Wound thereon.

Another object of the invention is to provide 'an improved cold permanent wave rod that is adapted kto be contracted to relieve tension on the hair wound thereon and in. which means is provided for retaining hair in position on the rod.

A further object of the invention is to provide an improved hair curler in which means is provided for relieving tension in hair wound thereon to facilitate lotion penetrating through the wound hair in which the curler is of a simple and economical construction.

With these and other objects and advantages in View, the invention embodies an elongated cylindrical shaped rod having a concave intermediate section with enlarged ends, with elastic elements extended around the ends, with a spreading element extended into the intermediate part of the curler, and with hair gripping clips mounted on the outer surface of the curler.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure l is a View illustrating the improved cold permanent wave rod with hair wrapped thereon.

Figure 2 is a plan View showing the improved curler or rod.

Figure 3 is a side elevational view of the device showing the rod with the sections thereof in spaced rel-ation.

Figure 4 is ya side elevational view similar to that shown in Figure 3 showing the device with the sections contracted.

Figure 5 is a cross section taken on line 5-5 of Figure 4 Ishowing one end lof the curler.

Figure 6 is a :similar section taken on line 6 6 of Figure 3 showing `one end of the rod With the parts expanded.

Figure 7 is a detail showing a longitudinal section through one end of the rod with the parts contracted and with a hair gripping clip at one end of the rod extended through an opening in the end of the rod.

Figure 8 is a detail showing a longitudinal section through part of the rod with the parts expanded and with the hair gripping clip positioned against the outer surface of one end of the rod.

Figure 9 is a cross section taken on line 9-9 of Figure 8 showing the intermediate or spreading section of the rod.

The cold permanent wave rod of this invention, which may be made of wood, plastic, rubber, aluminum, or other suitable material, permits curls larger than are possible on conventional permanent wave rods, as by Winding the hair on an expanded rod and contracting the rod with the hair wound thereon, tension is relieved in the strands of hair wound on the rod so that more eicient and effective penetration of the hair waving solutions through the hair wound on the rod is obtained.

Relieving the tension in the strands of hair wound on the rod so that the curl is not tight speeds up the timing for processing permanent waving thereby reducing the time required for a permanent wave considerably.

The improved cold permanent Wave rod of this invention, therefore, makes it possible to givenpermanent waves more rapidly and the process is not only useful by professionals in beauty parlors but can also be used ellciently and effectively for home cold permanent waves.

Also by providing means for reducing the diameter of the rod after the hair is wound thereon, the tension in the strands of hair is relieved, and as the strands are not tight more efficient penetration of hair waving lotion is obtained, and larger curls may be made on a rod.

Referring now to the drawing wherein like reference characters denote corresponding parts the improved cold permanent wave rod of this invention includes `a pair of complementary lsemi-circular sections 10 and 11, a wedge 12 positioned to coact with surfaces 13 and 14 in the intermediate part of the rod, elastic bands 15 and 16 for urging the sections of the rod together, a clip 17 pivotally connected to the surface of the section 10 of the rod with a hinge 18 and hair gripping fingers 19 and 20 positioned to extend over hair wrapped on the rod.

The sections 10 and 11 are comparatively thin metal shells having lopenings or perforations, as indicated by the numeral 21 through the walls thereof and the outer surfaces of intermediate portions may be knurled as shown at the points 22 and 23 to facilitate gripping ends of hair thereon.

The section 10 is provided with flanges 24 and 2S at the ends and the flanges `are provided with notches, as indicated by the numeral 26 through which the hair gripping fingers 19 and 20 extend. The section 11 is`provided with similar flanges 27 and 28 and the flanges of this section are also provided with notches as indicated by the numeral 29.

The cam surfaces 13 and 14 are formed on segments 30 and 31 in the intermediate portions of the sections and recesses 32 and 33 are provided adjacent the cam surfaces whereby upon inward movement of the wedge 12 the wedge moves into the recesses permitting contraction of the sections and 11. i

The wedge 12 is provided with a stem 34 that extends from one. end of the rod and the end of the stem is provided with a head 35.

The sides of the ysection 10 are also provided with lugs 36 that are positioned to extend into recesses 37 which locate these sections longitudinally, it being understood that the device shown in Figure 3 is illustrated on an enlarged scale and the opening movement of the sections is comparatively slight whereby the lug 36 remains in the recess 37.

The flanges 25 and 28, at one end of the rod are provided with openings 38 and 39, respectively, whereby the linger may be inserted in the end of the rod, as illustrated by the finger 19 in Figure 7. and the openings also provide means for attaching a string or cord that may be extended over hair wrapped on the curler with the free end of the string or cord secured in corresponding openings or notches, such as the notches 26 and 29 at the opposite end of the rod.

The liange of the section 10 is also provided with a U-shaped washer 40 that is adapted to extend over the stem 34, as illustrated in Figure 6 to provide means for locating the ends of the sections and also means for positioning one section in relation to the other.

The liange 24 at the opposite end of the section 10 of the rod is provided with a button 41 by which the linger 19 is mounted on the end of the section and, particularly as illustrated in Figure 7, the finger 19 is provided with a flange 42 having a head 43 on the outer surface and a button 44 on the inner surface and a band 45 of elastic material connects the buttons 44 and 41. With the finger 19 secured to the rod with the elastic member 45 the linger may be positioned in an opening 46 in the end of the ange 24 or may extend through one of the notches in the peripheralsurface, as shown in Figure 3.

The finger 20 is secured to the oppostie end of the rod in a somewhat similar manner with an elastic element 47 secured to a button 48 on the head 35of the stem 34 and also on a button 49 of a ange S0 extended from the nger 20. A head 51 is provided on the outer surface of the ange 50 to facilitate withdrawing the linger 20 from an opening 38 and also to facilitate positioning the linger in notches, such as the notches 26.

The sections 10 and 11 are provided with semi-circular recesses 52 and 53 in which the band 15 is positioned, as shown in Figure 7 and also similar recesses 54 and 55, respectively, in which the elastic band 16 is positioned, as shown in Figure 8.

With the parts arranged in this manner and with the sections 10 and 11 spread by the wedge 12, as illustrated in Figure 3, the ends of a curl of hair are secured on the surface with the clip 17 which may be mounted with a spring hinge or the like on the section 10 and after the hair is wrapped on the rod the fingers 19 and 20 are positioned over the hair or the hair may be tied with a string or the like.

With the hair in position upon the rod the wedge 12 is pressed inwardly whereby the sections 10 and 11 are moved to the contracted positions as illustrated in Figure 4 by the elastic bands 15 and 16 and with the parts in this position tension in the hair wrapped on the rod is released whereby wave lotion or other liquid applied to the curl penetrates through the strands of the hair.

It will be understood that modifications, within the scope of the appended claim may be made in the design and arrangement of the `parts without departing from the spirit of the invention.
